Effusive-Constrictive Pericarditis due to Immune Reconstitution Inflammatory Syndrome following Tuberculous Pericarditis.

• Tuberculous pericarditis is the most common cause of pericarditis worldwide. • Consider the possibility of TB-IRIS in patients with tuberculous pericarditis. • Corticosteroids might be necessary, but there are several caveats to consider.

Real-time left ventricular pressure-volume loops during percutaneous mitral valve repair with the MitraClip system.

Background: Percutaneous mitral valve repair with the MitraClip device has emerged as an alternative to surgery for treating severe mitral regurgitation. However, its effects on left ventricular loading conditions and contractility have not been investigated yet.

Methods And Results: Pressure-volume loops were recorded throughout the MitraClip procedure using conductance catheter in 33 patients (mean age, 78±10 years) with functional (45%), degenerative (48%), or mixed (6%) mitral regurgitation.
